WICK-RAI SING DEVICE.

SPECIFICATION forming part of Letters Patent No. 484,981, dated October 25, 1892.

Application filed July 12, 1892.

T0 at whom it may concern:

Be it known that I, HUGH L. SMITH, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Tick-Raising Devices for Oil-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in wick-raising devices; and the invention consists in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described.

In the drawings, Figure 1 is a vertical central section through the base of an oil-stove embodying my invention. Fig. 2 is a crosssection on line as a: in Fig. 1. Fig. 3 is a detached perspectiveview of the wick-ring,showing my raising and lowering device attached thereto. Fig. 4 is a vertical section on line y y in Fig. 2. Fig. 5 is a perspective view of the parts forming the wick raising and lowering device.

A is the base of the stove.

B is the oil-tank, preferably in the shape of a ring supported within the base, the top of the stove not being shown.

C is the annular wick-chamber, formed by the wick-tubes 0' C supported in any desired manner within the central aperture in the oil-tank and connected thereto by a supplychannel D.

E and F are tubes arranged concentrically to the wick-chamber 0 inside and outside thereof, respectively, forming air-passages a, b, c, and (Z, the passage a being between the tube E and the tank, the passage 1) between the tube E andthe wick-chamber C, the passage 0 being between the wick-chamber and the tube F, and the passage (1 within the tube.

F, giving an air-supply upon both sides of the wick-chamber and the large central air-supply within the wick-tube.

G is the wick, of cylindrical shape and adapted to enter the wiclccharnber, being secured upon a metallic wick-raising sleeve H by means of a suitable cord 1 or in any other desired manner.

The wick-raising sleeve at one side is provided with an offset J, forming a guide for Serial No. 439.7%. (No model.)

the rack employed in raising and lowering the wick. This guideway is provided at the top with a cross-bar e and at the bottom with a cross-bar f.

K is a rack having a gain formed at one side, in which the upper end of a bar L engages, and is secured by riveting or in any other desired manner, so that the side of the bar and the side of the rack will be flush with each other. This bar has an extension N extending upward to the upper end of the rack and substantially parallel therewith, having the ofiset O and the finger-piece P at the upper end, the whole forming a substantially- U-shaped construction, having the rack in one vertical portion and a spring-arm forming the other, with a hook or ofiset at the top of the spring-arm, the length of this device be ing substantially the length of the wick-raising sleeve H. In constructing the stove the rack-bar portion is engaged into the guideway J, while the spring-arm M extends up outside of the guides e and f within the wickchamber.

Q is a pinion engaging with the rack K, secured to the end of a shaft Q, having a suitable hand-wheel R for actuating the same, and preferably j ournaled in a guide-casing S, extending to the side of the stove.

To put the wick into the stove, the operator turns the hand-wheel R, raises the rack with its spring-arm to the top of the wick-chamber, in which position the rack, with its springarm, will project above the top in convenient position for him to withdraw the spring-arm from the rack and engage the wioleraising sleeve with its wick into, the wick-chamber, the spring-arm being inside of the wick-raising sleeve. The wick-raising sleeve is lowered until it reaches the bottom of the V- shaped frame, when the operator releases his hold of the spring-arm. The ofiset 0 will engage over the top of the wick-raising sleeve and prevent its disengagement except upon the withdrawal of that offset therefrom. Now if the operator turns the hand-wheel R in the opposite direction from the direction in which he has previously operated it the rack-bar will be lowered, and with it the spring-arm N, and by the engagement of the offset 0 upon the top of the wick-raising sleeve this sleeve and the wick will be carried downward. The

upward movement of the wick-raising sleeve will carry the wick with it because of the engagement of the Wick and wick-raising sleeve within the U-shaped frame.

What I claim as my invention is 1, In a Wick raisingand loweringidevice, the combination of the wick and the wickraising sleeve upon which it is secured, of a U-shaped frame embracing the wick-raising sleeve at the lower end, a rack-baron one arm of the frame, an cifset portion engaging the top of the raising-sleeve on the other arm, and a pinion engaging the rack, substantially as described.

2. In a wick raising and lowering device, the ecmbinatiomwith the oil-tube having a HUGH L. SMITH.
